Does Allah Need Us to Go Through Others When We Call upon Him?

Is Allāh the Mighty and Majestic in need of having an intermediary taken between himself and a slave?

Allāh the Mighty and All-High is near and ever-responding. He hears and sees, grants mercy and all kinds of good, and accepts repentance from His slaves. And He has not commanded us to set up intermediaries when calling upon [Him]; rather, He commanded us to call upon Him directly:

فَادْعُوا اللَّهَ مُخْلِصِينَ لَهُ الدِّينَ

So call upon Allāh [singly], making all worship and acts of obedience purely for Him alone. (Extract from Al-Ghāfir 14, English explanation)
